SOLDERING-IRON Specicaton of Letters Patent.

Fatented Nov. 2&5, 1918.

' pplcation filed December 29, 19K. Serial Io;29,502.

State ot' Pennsylvania, have invented a new and useful Soldering-Iron of which the following is a specification.

This invention has reference to soldering irons, and its object is to provide a soldering iron in which means for heating the iron forni part thereof. A n

The invention comprises a soldering head which may be of copper as is customary, such head being hollow and open at one side Where it is provided with a perforated or reticulated cover so Aarranged as to permit the escape of gases of combustion. The heat is carried by a hollow body member having a tortuous duct for fuel, and a needle valve for controlling the tlow of fuel. The body member and head are carried by the pi' e leading to a fuel reservoir constituting tie handle of the soldering iron, so that it is unnecessary to provide a stove or similar means for heating the iron, and the latter may be kept at an even temperature, while the soldering operation is proceeding.

The invention will be best understood from a consideration ot' the following detailed description, taken in connection with the accompanying drawings forming part of this specification, with the further understanding that, while the drawing shows a practical form of the invention, the latter is not confined to any strict conformity .with the showing ofthe drawing but may be changed and modified so long as such changes and modiiications come within the scope ot the appended claims.

In'the drawingzw Figure 1 is a side elevation ot a soldering iron constructed in accordance with the invention;

Fig. 2 is a longitudinal central Uaction oi. the reservoir end ot' thesoldering iron;

Fig. 8 is a longitudinal section with some parts iii elevation of the head eid of the soldering iron;

Fig. 5 is a cross `section of the reservoir end, omitting the pum Fig. 6 is 'a cross section of the reservoir end, with the section traversing the pump,

a soldering iron head 1 which may be of the usual pyrainidal forni, and may also be made of copper, a'tter the customary practice. Tithin the head 1 there is t'ornied a chamber 2 leaving the walls ot' the head relatively thin, since, as will hereinafter appear, heat is localized immediately hack of the soldering end ot' the head, and is there maintained, thus doing away with the necessity ot' providing a relatively large mass ot' metal at the head to store sul'licient heu for the soldering operation. That end of the head 1 remote from the soldering point is i'ornied into a socket 3 communicating with the chamber L through a passage el of relatively large area. The chamber 2 is open along one side, as shown at 5, throughout substantially the t'ull length and lwidth of the chamber, and the opening' is covered by a plate 6 which may be perforated or retieulated as shown at 7 and is supported by a series of wires or bars 8 driven or otherwise connected at the ends to the body of the head 1. The cover (i protects the chamber 2 from direct access, but permits the ready escape ot' the products of combustion, distributing such products ot' combustion throughout the chamber, and preventing localized escape thereof. This results in a thorough heating ot' the head 6 throughout practically the whole mass ot' the head and particularly toward the point where the head is most efficiently utilized.

Fitted into the socket 3 and held there by a pin 9 or otherwise, is a body member 10 ot elongated form and hollow throughout its length. The body member is closed in most part except at the ends, and along one side is formed with an offset boss 11 in wvliich there is a chamber 1i?. At one end the boss 11 is formed with a screw nipple 13 and at. thc other end with a screw socket 14. The nipple 13 has a gland or'thimble nut 15 applied thereto` holding one end oi a pipe 1G to the nipple. At the other end ot' the boss 11, the socket 1i receives a nipple 17 on one end of a pipe 18, to which latter reference will hereinafter be made. t'

The. pipe 16 is carried through a suitable opening 19 in the corresponding portion of the body member 10, 'and is formed into a coil 2O within and extending lengthwise o1" the body memberlO.' At the end remote from the head 1, the body member' is formed with a prolongation or lip 21 terminatingin aI thickened portion 22 so that the part ot' the body portion 10 provided with the lip 21 The nozzle 2l is arranged axially of thev c oil'and is directed toward the passage .4

through which theinterior of the body 10 communicates with 'the chamber 2.

The pipe 18 is ol' suliicient diameter and length 'to constitute the shank portion of' the 'soldering iron, and at an intermediate point is formed into a loop'26 extending substantially lengthwise of the shank, and may, as shown, consist of a single turn located about midway of. the shank between the reservoir27 and the soldering iron head.

At the end of the shank 18 remote from the body portion 10, ith-as attached to it a reservoir 27 which, at the front end, may be of ('val cross section as indicated at 28 in Fig. 5', while at the rear end, it is of round cross section as indicated at 29 in Fig. 6. The oval cross section is convenient for grasping bythe hand, While the round cross section is utilized for the application of a cap 30 which is screwed onto the reservoir 27, so that it constitutes a filling cap for the reservoir.

The cap 30 carries a pump 31' with a manipulating handle 52 exterior to the cap, While the pump 3l is lodged within the reservoir 27. T he pump lrequires no special description, since it may follow the lines of the usual air pumps employed in torches for producing air pressure to drive liquid fuel to the burner.

The reservoir 27 has a nipple 33 at the end remote from the cap 30, and close to one side of the reservoir and the pipe or shank 18, has a socket end 34 screwed onto the nipple. lVithin the nipple 33, which is hollow, there is lodged a head 35 formed on one .end of' a pipe 3G of suliicient-length to enter the reservoir 27 and extend :inappropriate distance toward the other endl threo, the head 35A having the end remote from the pipe 36 formed With a relatively sharp edge 37 to produce a fluid-tight joint Where engaged by the socket 34. v

The shank 18 extends in the direction of y the length of the body member 10, but to one side of the longitudinal axis thereof,so that when the solderingiron head l rests upon a supporting surface, the shank 18 extends lengthwise of the surface but elevated above it, while the reservoir 27 also extends length- Wise ol:l the same surface and still farther elevated above it. To support the solderlugs 41 are provided on opposite sides of the reservoir in the path of the legs of the yoke so that the yoke may snap over these lugs and be held in the inactive position.

Considering the reservoir 27 as containing a supply of 'fuel and the -needle valve 25 as closed, air pressure is established Withinthe reservoir by the pump 31 int-he usual manner, 'and suitable priming liquid is placed inthe body portion 10 and ignited.

When the coil 20 has become sufficiently.'l

heated,'the needle valve 25 is opened, per' mitting liquid from the reservoir 28 to iloW.'

through the pipe 18, and this liquid is gasi-A fied when it reaches the coil 20, liovving through' the nozzle'24: in the form of gas, and becomes ignited when it is passing-through the coil, maintaining the latter heated, and enters the chamber 2 and escapes through the opening thereof in the form of an intensely `hot flame Well distributed through the,

chamber 2 and against' the point portion of the head 1, the result being that the soldering iron head becomes sufficiently heated, and by 1iulq'usti'ng the valve 25, the heat may be maintained at a desired temperature.'

The pipe 36 permits the maintaining of a. flow ot' fuel to the burner when the soldering iron is held in an upright position, that is, with the soldering head uppermost, and

the pipe 36 may be as long as needful for the purpose. The coil 26 localizes a small supply of uel to prevent the stoppage of the iia'me under some. circumstances, and the chamber 12 also localizes fuel `for the same purpose, The soldering iron may be carried in a workmans kit, land requires no plumbers furnace or other separate peating means. The` reservoir conveniently its the hand, andno filling plug and separate itting for the pump are required. The solderingiron may be placed upon@l support 'with the reservoir high, while the soldering iron is approximately level, because of the presence ofthe yoke 3S, the latter being capable .of movement outof the Wayivhen the soldering iron is in use.

The soldering iron head may be made light. using but little material, because the head is brought very close to the Working point ot the iron. Furthermore, the small amount ot' material necessary in the head, beside reducing the cost oi' manufacture, prevents conduction of heat to the shank, so that iviile the soldering iron is in use, the shank, even at a relatively short distance from the head, is quite. cool.

In order to give free escape of. the gases ot combustion from the chamber V:2 and still thoroughly distribute these gases Within the chamber`r the plate (i is provided with a. iring'e about its edge portions, suchfringe i5 being indi -d at l2 and may be formed integral with What is c l.
